2 Safety
2.1 Intended use
1. Zeverlutionconverts the direct current from PV arrays into grid-compliant
alternating currentand feeds it into the utility grid.
2. Zeverlution must only be operated by qualified persons with the appropriate skills
who have already read and understood all documentation relating to its
installation, commissioning, operation and maintentance.
3. Zeverlutionis suitable for indoor and outdoor use.
4. Zeverlutionmust only be operated with PV arrays (PV modules and cabling) of
protection class II, in accordance with IEC 61730, application class A.
Do not connect any sources of energy other than PV modules to the inverter.
5. PV modules with a high capacity to ground mustonlybe used if their coupling
capacitydoes not exceed 1.0μF.
6. When exposed to sunlight,the PV array generates dangerous DC voltage which is
present in the DC conductors and the live components of the inverter. Touching the
DC conductors or the live components can lead to lethal electric shocks.
7. All components must remain within their permitted operating ranges at all times.
2.2 Safety standards
Zeverlutioncomplieswith the EU Low-Voltage Directive 2006/95/EC and the EMC
Directive 2004/108/EC.
Zeverlution also complies with the requirements for safety and EMC in Australia and
NewZealand markets.
The inverter is labeled with the CE mark and RCM mark.

2.3 Important safety information
• All work on the inverter must only be carried out by qualified personnel who
have read and fully understood all safety information contained in this
document.
• Children must be supervised to ensure that they do not play with this device.
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DCvoltage which
is present in theDC conductors and the live components of the inverter.
Touching the DC conductors or the livecomponents can lead tolethal electric
shocks. If you disconnect the DC connectors from theinverter under load, an
electric arc may occur leading to electric shock and burns.
•Do not touch non-insulated cable ends.
•Do not touch the DC conductors.
•Do not touch any live components of the inverter.
•Have the inverter mounted, installed and commissioned only by qualified
persons with theappropriate skills.
•If an error occurs, have it rectified by qualified persons only.
•Before assembling the DC connectors, please first cover the PV modules
with opaque material..
•
Prior to performing any work on the inverter, disconnect it from all voltage
sources asdescribed in this document (see Chapter 8).

5 Installation and Operating Instructions V04
Risk of injury due to electric shock and fire caused by high leakage
current
• The inverter must be reliably grounded in order to protect property and
personal safety.
Risk of injury due to hot heat sink
• The heat sink may get hot during operation. Do not touch!
Possible damage to health as a result of the effects of
electromagnetic radiation
• Please maintain a distance of at least 20cm from the inverter when it is
inoperation.
Grounding the PV array
• Comply with local regulations for grounding the PV array.
We suggest the frames of PV modules must be reliably grounded.
•Do not ground any of the terminals of the PV strings.

Installation and Operating Instructions V04 6
Damage to the seal of the cover in sub-zero conditions
•If you open the cover in sub-zero condition,the sealing of the cover can be
damaged. This can lead moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5℃.
• If a layer of ice has formed on the seal of the cover in sub-zero conditions,
remove it prior to opening the inverter(e.g. by melting the ice with warm
air).Observe the applicable safety regulation.
Damage to the inverter due to electrostatic discharge
•Touching electronic components can cause damage to or destroy the inverter
through electrostatic discharge.
• Ground yourself before touching any component.

13 Installation and Operating Instructions V04
4.3 Mounting the inverter with the wall bracket
Mounting procedures:
1. Use the wall bracket as a drilling template and mark
the positions of the drill holes, then drill 2 holes (Φ10)
to a depth about 70mm. During operation, keep the
drill vertical to the wall, and hold the drill steady to
avoid tilted holes.
2.After cleaning the holes, place the 2 wall anchors into the holes, then attach the
wall bracket to the wall using the hexagon head screw delivered with the inverter.
Risk of injury when lifting the inverter, or if it is dropped
The inverter weighs approximately 11kg. There is risk of injury if the inverter is
lifted incorrectly or dropped while being transported or when attaching it to or
removing it from the wall bracket.
• Transport and lift the inverter carefully
Risk of injury due to damaged cables
There may be power cables or other supply lines (e.g. gas or water) routed in the
wall.
• Ensure that no lines are laid in the wall which could be damaged when drilling
holes.

Installation and Operating Instructions V04 14
3.Hold the inverter using the housing side edges and attach it onto the wall bracket
tilted slightly downwards.
4. Check both sides of the heatsink to ensure that it is securely in place.
5.Pushthe inverter inwards as far as possible and attach it to both sides of the wall
bracket using the M5 screws(screwdriver type: T25,torque: 2.2Nm).

5 Electrical connection
5.1 Safetyduring Electrical Connection
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage which
is present in theDC conductors and the live components of the inverter.
Touching the DC conductors or the livecomponents can lead tolethal electric
shocks. If you disconnect the DC connectors from theinverter under load, an
electric arc may occur leading to electric shock and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by
qualifiedpersons with the appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Before assembling the DC connectors, please first cover the PV modules with
apaque material.
• Prior to performing any work on the inverter, disconnect it from all
voltagesources as described in Section 8.
